But sadly, Madi ended up back in the ICU this week at Dana-Farber Boston Children’s Cancer and Blood Disorders Center and she won’t be able to go to the concert.

Madi’s focused on the positives, such as ice cream sundaes in her hospital bed. But her mom was bummed, and posted a message on Facebook asking if anyone wanted to buy the tickets, figuring she could use the money to do something special with Madi once she feels better.

"To see that there’s so much good in so many people and that they care, Madison has an army of people behind her," Shauna said.

Shauna says while it would be awesome to see the sparkle in her daughter’s eye from meeting her favorite band, she has much bigger hopes and dreams for her little princess.

"I want to see her grow up to be normal and I’m sorry," said Shauna tearing up, "I just want to see her be -- the range of normal – there is no range and this is our normal, but I want her to grow healthy, I want her to grow happy."
